GUARANTEE OF PAYMENT AND PERFORMANCE OF OBLIGATIONS. ---------------------------------------------------- (a) For value received, Pathnet Telecommunications, Inc. (the "Parent") unconditionally guarantees to the holder of any Outstanding Note or Notes (a "Holder") the full and punctual payment and performance of the Obligations (as defined in subsection (b) below). This Guarantee is an absolute, unconditional and continuing guarantee of the full and punctual payment and performance by the Company of each of the Obligations, and not of collectability only, and is no way conditioned upon any requirement that any Holder first attempt to seek payment or performance from the Company or any other guarantor or surety or resort to any security or other means of obtaining payment of all or any of the Obligations or upon any other contingency. Upon any default by the Company in the full and punctual payment or performance of any of the Obligations, if such default remains uncured after the giving of any required notice and after any applicable period of cure, the liabilities and obligations of the Parent hereunder shall at the option of any Holder become forthwith effective, matured, due and payable without further demand or notice of any nature, all such demands and notices being expressly waived by the Parent. (b) As used herein, the term "Obligations" means all obligations,covenants, liabilities, undertakings and agreements of any kind of the Company to all or any of the Holders contained in the Indenture, to be performed after the date hereof, howsoever, incurred, arising or evidenced, whether now or hereafter existing, due or to become due or of payment or performance and including, without limitation: (i) the prompt payment in full, in United States currency, when due (whether at stated maturity, by acceleration, by mandatory or optional prepayment or otherwise) of the principal of and interest on the Notes (including interest on any overdue principal, and, to the extent permitted by applicable law, on any overdue interest) and all other amounts from time to time owing by the Company under the Indenture and under the Notes (including costs, expenses and taxes); and (ii) the prompt performance and observance by the Company of all covenants, agreements and conditions on its part to be performed and observed under the Indenture, in each case strictly in accordance with the terms thereof (such payments and other obligations being herein collectively referred to as the "Obligations"). 2. GUARANTEE CONTINUING AND LIABILITY UNAFFECTED. (a) Subject to Section 2 (c), this is a continuing guarantee and shall be binding upon the Parent regardless of how long before or after the date hereof any part of the Obligations was or is incurred by the Company. Subject to Section 2 (c), this Guarantee may be enforced by any or all of the Holders from time to time and as often as occasion for such enforcement may arise. (b) If after receipt of any payment from the Parent made hereunder the Holders, or any of them, are compelled to surrender or voluntarily surrender such payment or proceeds to any person because such payment or application of proceeds is or may be avoided, invalidated, recaptured, or set aside as a preference, fraudulent conveyance, impermissible setoff or for any other reason, whether or not such surrender is the result of (i) any judgment, decree or order of any court or administrative body having jurisdiction over the Holders, or (ii) any settlement or compromise by the Holders of any claim as to any of the foregoing with any person (including the Company), then the Obligations or part thereof affected shall be reinstated and continue and this Guarantee shall be reinstated and continue in full force as to such Obligations or part thereof as if such payment or proceeds had not been received. The provisions of this Section 2(b) shall survive the termination of this Guarantee and any satisfaction and discharge of the Company by virtue of any payment, court order or any federal or state law. (c) The Parent shall be subrogated to all rights of the Holders in respect of any amounts paid by the Parent pursuant to the provisions of this Guarantee; provided, however, that Parent shall be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation with respect to any Obligation only after the payment of all amounts owed by the Company to the Holders with respect to all of the Obligations have been paid in full. (d) This Guarantee shall terminate and be of no further force and effect as to any Note upon full payment of the Redemption Price with respect to such Note, PROVIDED, however, that this Guarantee shall continue to be effective or shall be reinstated, as the case may be, if at any time the Company must restore payment of any sums paid under such Note or under this Guarantee for any reason whatsoever. 3.
